部分資訊涉及發行前產品,在發行之前可能會有大幅修改。 Microsoft 對此處提供的資訊,不做任何明確或隱含的瑕疵擔保。
在 EF 想要呼叫 之前呼叫 RollbackAsync(CancellationToken) 。
public System.Threading.Tasks.Task<Microsoft.EntityFrameworkCore.Diagnostics.InterceptionResult> TransactionRollingBackAsync (System.Data.Common.DbTransaction transaction, Microsoft.EntityFrameworkCore.Diagnostics.TransactionEventData eventData, Microsoft.EntityFrameworkCore.Diagnostics.InterceptionResult result, System.Threading.CancellationToken cancellationToken = default);

Public Function TransactionRollingBackAsync (transaction As DbTransaction, eventData As TransactionEventData, result As InterceptionResult, Optional cancellationToken As CancellationToken = Nothing) As ValueTask(Of InterceptionResult)

參數
- transaction
- DbTransaction
異動。
- eventData
- TransactionEventData
連線和交易的相關內容資訊。
- result
- InterceptionResult
如果存在,則表示目前的結果。
如果某些先前的攔截器藉由呼叫 Suppress() 來隱藏執行,這個值將會 IsSuppressed 設定為 true
。
這個值通常用來做為這個方法實作的傳回值。
- cancellationToken
- CancellationToken
CancellationToken等候工作完成時要觀察的 。
傳回
如果 IsSuppressed 為 false
,則 EF 會如常繼續。
如果 IsSuppressed 為 true
,EF 將會隱藏即將執行的作業。
未嘗試隱藏作業之任何攔截器的這個方法實作是傳回 result
傳入的值。
